  • $mail->SMTPAuth = true; – Enable SMTP authentication
  • $mail->Username = ‘rintoug@gmail.com’; – SMTP username, will be your Gamil username
  • $mail->Password = ‘intogteldir123#’; – SMTP password, will be Gmail password
  • $mail->SMTPSecure = ‘tls’; – Enable TLS encryption, ssl also accepted
  • $mail->Port = 587;

Normal cases this is enough to get working. But when you use Gmail’s SMTP settings, you have to set this truseted app in Gmail control panel.
